[GRASS-user] Obtaining unique nodes from a topology

Hi all

I've used Grass to build a topology out of a polygon shapefile, so far so
I now need to export it as an arc-node topology (i.e. boundaries  with
startnode_id, endnode_id) which I will then use in PostGIS.

Does anyone know of a way to get the nodes from the topology and attach
these attributes to the boundaries?
I know I can get the start/end coordinates, but I need the unique nodes and
their ids.
